Answer:
The farthest distance is
Explanation:
The angular resolution is mathematically represented as
Where Z is the distance between the car head lamp with a value Z = 1.4 m
L is the distance between the eye and the car
is the wavelength with a value 500 nm =
d is the diameter of the eye with a value d = 0.50 cm =
The maximum distance is given as

The final momentum is 20.00 kg*m/s
Explanation:
The momentum of an object is given by:
where
m is the mass of the object
v is its velocity
For the object in the problem, the initial momentum is
Then, the mass is doubled:
m' = 2m
And the velocity is also doubled:
v' = 2v
So, the new momentum will be:
So, the final momentum is 4 times the initial momentum.

Answer: hello your question is incomplete attached below is the complete question
answer : 1/2 KD^2 ( option A )
Explanation:
P.E ( potential energy ) = mgd
In case 1 P.E = 0 i.e. mgd = 0
Given that in case 2 the Mass M had moved through the Distance D by the compression of the spring
<u>The potential energy of the M in case 2 </u>
= P.E of M at rest + P.E of the spring
= 0 + 1/2 KD^2
